Scott Disick stopped by Little Blue gourmet market in Calabasas yesterday, and hopefully the Keeping Up With the Kardashians star chowed down, because we've never seen him look so skinny!

Maybe the stress of having two kids is catching up with him? The New York native just welcomed newborn daughter Penelope in July, and between filming a reality show, running a restaurant, and parenting his brood he's got to be exhausted!

With Lamar Odom and Kanye West to compete with, Mr. Disick better start pumping some iron!
